ios - RCTLinking > 问题 > 指针缺少可空性类型说明符(_Nonnull、_Nullable 或 _Null_unspecified)

Question

只是好奇自 XCode 版本 10.2 (10E125) 更新以来是否还有其他人得到这个并知道修复？

• macOS Mojave 10.14.3 (18D109)
• “ native react ”:“0.57.0”
• 节点 v11.6.0
• npm: 6.5.0-next.0
• yarn :1.14.0-20181221.0548

Answer 1

最后归结为 RCTLinkingManager.h。

我用非空断言修改了它，如下所示:

/**

 */

#import <UIKit/UIKit.h>

#import <React/RCTEventEmitter.h>

@interface RCTLinkingManager : RCTEventEmitter

+ (BOOL)application:(UIApplication *_Nonnull)app
            openURL:(NSURL *_Nonnull)URL
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *_Nonnull)options;

+ (BOOL)application:(UIApplication *_Nonnull)application
            openURL:(NSURL *_Nonnull)URL
  sourceApplication:(NSString *_Nonnull)sourceApplication
         annotation:(id _Nonnull )annotation;

+ (BOOL)application:(UIApplication *_Nonnull)application
continueUserActivity:(NSUserActivity *_Nonnull)userActivity
 restorationHandler:(void (^_Nonnull)(NSArray * __nullable))restorationHandler;

@end

现在构建成功。
